Sažetak
Žumberak and Samoborsko gorje in Croatia and Gorjanci in Slovenia respectively are a mountain range bordered by the rivers Krka, Sava and Kupa and represent a Croatian - Slovenian transboundary aquifer. The area of research was Croatian part of the mountains - protected as a Nature Park. It stretches over 342 km2 rising from 180 to 1178 m above sea level (Sveta Gera or Trdinov Vrh). The main part of Žumberak consists of Upper Triassic dolostones (46 %) and Upper Cretaceous carbonates or flysch (35 %). Until now, 137 caves were explored in this border area of the Dinaric karst. During the last four years a comprehensive hydrogeological research was carried out to determine the hydrogeological characteristics of the Samoborsko gorje and Žumberak area. The first stage of the research resulted in 847 mapped springs whose basic physico-chemical parameters and discharge „in-situ“ were measured at least once. The seasonal water balance was calculated on the basis of measured spring’s data, precipitation, air temperature, evapotranspiration and discharge data of the main watercourses of the rivulets Kupčina, Bregana, Lipovečka Gradna and Rudarska Gradna. Calculations for the entire researched area and for the researched area without impermeable rocks indicate the greatest losses at the western Cretaceous flysch part where water flows at the surface or underground to Slovenia or Kupa River. These results are in accordance with a water tracer tests for this open hydrogeological system.
